An apparatus for separating particulate solids from liquids includes a blower which is mounted for rotation between two upright walls. A sieve surrounds the rotor with a spacing therefrom and a solid-liquid mixture to be separated is introduced onto a portion of the sieve. The flow of gaseous medium advanced by the blower is directed onto the sieve by an elongated curved guide element having one end close to the portion of the sieve, another end close to the blower in the region of the first-mentioned end, and a curved portion extending from the one to the other end around the blower opposite to the direction of rotation of the blower at a decreasing distance from the latter. The guide element bounds with the sieve a passage the flow-through cross section of which decreases in the direction of advancement of the gaseous medium which thus partly propagates along the passage and partly escapes therefrom through the sieve and thus entrains and expels the liquid from the mixture through the sieve. Breaking elements may be provided in the passage which disintegrate agglomerations formed during the propagation of the mixture through the passage. Detaching projections extend from an outwardly facing major surface of the guide element into the passage and serve to detach the flow of the liquid of the mixture from such major surface.

Apparatus for separating particulate solids from liquids

A continuous process for cleaning and preparing grossly soiled products of plastic material, such as sheets, bands, sacks or the like for subsequent re-use, in which the plastic material is comminuted after removing rough foreign objects therefrom, whereafter the comminuted plastic material is fed into a washing solution having a greater specific weight than the plastic material and subjected together with the washing solution in a washing zone to turbulence, transferred to a turbulence-free zone containing washing solution by passage under a submerged edge of a partition submerged in the washing solution and separating the washing zone from the turbulence--free zone, and thereafter subjected first to mechanical and then to a thermal drying operation.
